The video shows how a clean prompt can be turned into a complete video clip, how the three-stage rendering structure improves stability, and how to launch the workflow online without rebuilding the full ComfyUI environment locally.This ComfyUI workflow is designed for LTX 2.3 text-to-video generation, using OmniNFT, Relay-style prompt control, and the distilled 1.1 model route to create clean video outputs from text prompts. The main purpose of this workflow is to make text-to-video generation more controllable, more stable, and more suitable for publishing, especially when users want a no-subtitle, no-watermark, no-extra-text output.The workflow is built around the LTX 2.3 distilled 1.1 generation route. It uses an LTX 2.3 checkpoint, Gemma3-based text encoding, LTXVConditioning, EmptyLTXVLatentVideo, LTXVEmptyLatentAudio, LTX2_NAG negative guidance, ManualSigmas, CFGGuider, SamplerCustomAdvanced, LTXVLatentUpsampler, VAEDecodeTiled, LTXVAudioVAEDecode, and CreateVideo. The graph also includes seed control, fps control, universal negative prompting, VRAM management, and audio-video latent handling.The core idea is to generate video from text while maintaining stronger control over structure, motion, and final image quality. The positive prompt defines the subject, action, camera movement, lighting, environment, atmosphere, and cinematic direction. The negative prompt is designed to suppress common LTX video problems, including low quality, flicker, unstable perspective, identity drift, broken anatomy, subtitles, captions, UI overlays, logos, watermarks, unreadable text, and unwanted audio artifacts.The workflow uses a three-stage rendering structure. The first stage focuses on initial composition and motion foundation. It creates the base video latent and establishes the main visual direction. The second stage performs latent-space upscaling and refinement, allowing the workflow to improve structure and detail without rebuilding the whole video from scratch. The third stage applies final high-resolution polish, using another controlled sampling pass before tiled VAE decoding and video assembly.Compared with ordinary text-to-video workflows, this graph is more production-oriented. A simple one-pass T2V workflow may be fast, but it often suffers from weak motion, unstable composition, flicker, random text artifacts, or poor detail. This workflow separates generation into clear stages, uses negative guidance to suppress unwanted subtitles and watermarks, and applies latent upscaling before final output. That makes it more useful for creators who need cleaner video results for tutorials, showcases, social media, and workflow publishing.This workflow is suitable for cinematic shots, AI short clips, fantasy scenes, product-style motion, character motion tests, visual concept videos, MV fragments, Bilibili demonstrations, YouTube content, RunningHub showcases, and Civitai workflow examples. It is especially useful when you want to start from pure text but still keep the output clean and structured.Main features:<ul><li>LTX 2.3 text-to-video workflow</li><li>OmniNFT + Relay-style prompt control</li><li>Distilled 1.1 model route</li><li>Clean no-subtitle / no-watermark output direction</li><li>Gemma3 text encoder route</li><li>LTXVConditioning at controlled frame rate</li><li>Empty video latent and audio latent structure</li><li>LTX2_NAG negative guidance support</li><li>Universal negative prompt for clean video output</li><li>Three-stage rendering pipeline</li><li>LTXVLatentUpsampler high-resolution refinement</li><li>VAEDecodeTiled and CreateVideo final output</li></ul>Suggested workflow:Start with a clear text prompt. Define the subject, main action, camera movement, lighting, environment, and desired video style. Keep the first test short and avoid overloading the prompt with too many competing actions. If the output contains unwanted text, subtitles, logos, or unstable artifacts, strengthen the negative prompt and simplify the scene. If the motion is too weak, make the action and camera direction more explicit. If the composition is good but the detail is not enough, continue through the latent upscaling and final refinement stages. Once the three-stage result is stable, export the video and use it directly for publishing or further editing.⚙️ RunningHub WorkflowTry the workflow online right now — no installation required. 👉 Workflow: <a target="_blank" rel="ugc" href="https://www.runninghub.ai/post/2057671098963161090?inviteCode=rh-v1111">https://www.runninghub.ai/post/2057671098963161090?inviteCode=rh-v1111</a>If the results meet your expectations, you can later deploy it locally for customization.🎁 Fan Benefits: Register to get 1000 points + daily login 100 points — enjoy 4090 performance and 48 GB super power!📺 Bilibili Updates (Mainland China &amp; Asia-Pacific)If you’re in the Asia-Pacific region, you can watch the video below to see the workflow demonstration and creative breakdown. 📺 Bilibili Video: <a target="_blank" rel="ugc" href="https://www.bilibili.com/video/BV1yRGj6XEaM/">https://www.bilibili.com/video/BV1yRGj6XEaM/</a>☕ Support Me on Ko-fiIf you find my content helpful and want to support future creations, you can buy me a coffee ☕.
